After Cassie accepted membership of the new superhero group Slingers, she participated in an initiation rite. She was told to jump from the roof of one building to another. While her teammates had access to an array of powers to help them make the jump, Cassie did not. She fell to her death.
She was then reborn, no longer dead, but not exactly alive either. She was Dusk. Upon her revival, she found she had the ability to teleport anywhere via swirling shadows, as well as a precognitive ability that allowed her to feel where her teammates were, and if they were in danger. Later, she also developed the ability to manipulate shadows, as well as transport groups of people. Dusk wondered the earth after the team broke up.

One day, she received a psychic alert that her old teammate, Ricochet, was being attacked by an interdimensional being in Las Vegas. She quickly teleported there to save him. A man using the identity of their dead teammate, Hornet, told them the creature will only attack someone truly evil. Because it left them alone and primarily attacked Ben Reilly, they decided to team up with Hornet, eventually reunited with Prodigy as well.
